Underground Coal Fires
Coal burning deep underground in China,India and Indonesia is threatening the environment and human life , scientists have warned.These large-scale______(51)blazes（火焰）cause the ground temperature to heat up and kill surrounding vegetation,produce greenhouse gases and can______(52) ignite（点燃）forest fires , a group of scientists told the annual meeting of the American Association for the
Advancement of Science in Denver.The resulting______(53)of poisonous elements like mercury can also pollute local water sources and soils,they warned.
"Coal fires are a global disaster,"said Associate Professor Glenn Stracher of East Georgia College in
Swainsboro,USA.But______(54)few people know about them.
Coal can heat up on its own,and eventually catch fire and bum,if there is a continuous oxygen supply.The heat produced is not caused to______(55)and under the right combinations of sunlight and oxygen,can trigger spontaneous（自发的）catching fire and buming.This can occur underground , in coal stockpiles, abandoned mines or even as coal is transported.______(56)fires in China consume up to 200 million tons of coal per year,delegates were told.In______(57),the U.S.economy consumes about one billion tons of coal annually,said Stracher,______(58)analysis of the likely impact of coal fires has been accepted for publication in the International Journal of Coal Ecology.______(59)underway,coal fires can bum for decades,even centuries.In the process,they release large______(60)of greenhouse gases,poisonous fumes and black particles into the atmosphere.
